Name: MI350X
Brand: AMD

Question 1

What AI models can run on MI350X?

Accepted Answer

The MI350X (288 GB VRAM) can run models including gemma-4-E4B-it, gemma-4-26B-A4B-it, gemma-4-26B-A4B, gemma-3-12b-it, gemma-3-27b-it and more — 10 compatible models indexed so far. Compatible models are determined by whether the model's memory footprint fits within the GPU's 288 GB VRAM, potentially using quantization (Q8, Q6, or Q4) to reduce memory usage.

Question 2

What is the cheapest cloud option for MI350X?

Accepted Answer

We don't currently have cloud pricing data for the MI350X. This GPU may not be widely available from major cloud providers, or pricing data hasn't been synced yet.

Question 3

Is MI350X good for fine-tuning?

Accepted Answer

Yes, the MI350X is excellent for fine-tuning. With 288 GB of VRAM, it can handle full fine-tuning of models up to ~30B parameters and LoRA/QLoRA fine-tuning of much larger models. It's a top-tier choice for training workloads.

Question 4

How much VRAM does MI350X have?

Accepted Answer

The MI350X has 288 GB of VRAM (HBM3e). It also offers 8000 GB/s memory bandwidth, 2,500 TFLOPS of FP16 compute, FP8 support for efficient inference.

Question 5

What quantization formats work on MI350X?

Accepted Answer

The MI350X supports the following quantization formats: FP16 (full precision), FP8, Q8 (8-bit), Q6 (6-bit), Q4 (4-bit). FP16 works for models up to ~40B parameters. FP8 halves memory vs FP16 with minimal quality loss. Q4 quantization lets models up to ~979B parameters (by VRAM estimate) fit on the MI350X.
